Ambidextrous golf club

Abstract

A "Ambidextrous Golf Club Assembly" is designed to be used by a ambidextrous golfer. This same golf club is designed for right hand or left hand usage. This invention consist of a grip and shaft centerline that is attach to the head so that this centerline will intersect the center of gravity and the centerline of head, and The the head is designed to be symmetrical about a vertical plane that coincides with the centerline of the shaft. The centerline of the head is a line drawn from the center of gravity to a perpendicular line that is on the flat surface of the head or a perpendicular line that is tangent to a curved concaved or convex surface, and is parallel to the ground, and is at the same height as the center of gravity of the head. The sweet spot is where the centerline of the head will pierce the face of the head. This club head includes a highlighted straight line above and parallel to the center-line of the club head. This acts as a sight line to assist the golfer to align the club head to the center of the golf ball, and align the sight line to a imaginary line that goes from the center of the golf ball to its target. The center of gravity location can be changed by changing the weight and weight location of the head mass.

Description

DESCRIPTION OF THE PRIOR ART

[0001] A right hand golf club assembly is used by a right hand golfer. A left hand golf club assembly is used by a left hand golfer. This required two separate golf club assemblies. The center-line of the grip and shaft is located off center to the sweet spot and center-line of the head, and has a offset of 1.5-2.0 inches. This offset will produce a torsional deflection about the centerline of the shaft when the golfer drives a golf ball, which will cause the ball to travel to the left or right of its target (depending on a R.H. or L.H. golfer swing), The reason for the condition is that the sweet spot and the center-line of the club head makes contact with the golf ball and this offset (1.5 to 2.0 inches) produces a torque about the center line of the grip and shaft. This torque is great enough to cause the club head face to rotate about the center line of to grip and shaft, causing the golf ball trajectory to be right or left of its target. The same is true when a right or left hand golfer produces a divot. When the centroid of the divot is off center to the center line of the grip and shaft, it also produces a torque about the center line of the grip and shaft. The summation of both torques are great enough to cause the club head face to rotate about the center line of the grip and shaft, which causes the golf ball trajectory to be right or left of its target, depending on a right or left hand golfer.

BRIEF SUMMARY OF THE DISCLOSURE

[0002] The presently preferred embodiment of the invention of a "Ambidextrous Golf Club Assembly" consisting of a golf shaft and grip which is attached to the golf club head. The center line of the grip and shaft is attached to the club head so that its center-line will intersect with the center of gravity and the centerline of the club head, and the head is designed to be symmetrical about a vertical plane that coincides with the centerline of the shaft. The centerline of the head is a line drawn from the center of gravity to a perpendicular line that is on the flat surface of the head or a perpendicular line that is tangent to a curved concaved or convex surface, and is parallel to the ground, and is at the same height as the center of gravity of the head. The sweet spot on the club head face is where the center-line of the club head will pierce the club head face surface. This club head includes a highlighted straight line above and parallel to the center-line of the club head. This acts as a sight line to assist the golfer to align the club head with the center of the golf ball, and align it with a imaginary line that is going from the center of the golf ball to its target. The lie of the golf club is of any angle to the ground line. The centerline of the shaft is of any angle to the center-line of the head in the top and end view. The loft of the golf club is of any angle to the ground line. The claims for this invention are for any size golf clubs.

BRIEF DESCRIPTION OF DRAWING

[0003] The advantage of the "Ambidextrous Golf Club Assembly " will show that one golf club assembly is being used by a ambidextrous golfer. The following is a detail discussion and the accompanying drawings in which:

[0004] FIG. 1 is an elevation view of a golfer using a "Ambidextrous Golf Club Assembly".

[0005] FIG. 2 is a plan view of the golf head and shaft of the present invention with the shaft broken away.

[0006] FIG. 3 is a front view of the golf head and shaft of this invention with part of the shaft broken away.

[0007] FIG. 4 is a side view of the golf head and shaft of this invention with part of the shaft broken away.

DETAIL DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENT

[0008] Referring now to the drawings where in the presently preferred embodiment of this invention is illustrated. FIG. 1 discloses a "Ambidextrous Golf Club Assembly" 10 being used by any golfer. FIGS. 2, 3, and 4 contains a golf club head 12, and shaft 11. The center line 19 of the grip and shaft 11 is attached to the club head 12 so that it will intersect with the center-line 16 and the center of gravity 15 of the club head 12. The centerline 16 of the head 12 is drawn from the center of gravity 15 to a perpendicular line 21 that is on the flat face surface 18 of the head 12 or a perpendicular line 21 that is tangent to a curved concaved or convex surface 18, and is parallel to the ground 22, and is at the same height as the center of gravity 15 of the head 12. The sweet spot 14 is a spot where the center-line 16 of the head 12 will pierce the surface 18 at point 14. This club head 12 includes a highlighted straight line 13 above and parallel to the center-line 16 of the club head 12. and has a angle 23 of 90 degrees to line 21 in the top view FIG. 2. The lie angle 24 is of any degrees. The loft angle 25 is of any degrees. The center-line 19 of the shaft 11 to line 16 has a angle 20 of any degrees In the end view FIG. 4. This golf club head is symmetrical about a plane 17 that coincides with the centerline 19 of the club shaft shown in the end view FIG. 4. This invention is made of any material for any size golf club.

OPERATION

[0009] A ambidextrous golfer can use the same golf dub when being used as a right hand or left hand golf club. By aligning the sweet spot of the head with the center of the ball, and align the sight line of the club head, so as to coincide with a imaginary line that is drawn from the center of the ball to its target. He should re-grip the club shaft after this adjustment and keep the desired club head position that was set for the club head intact. He is now ready to drive the ball to its target. When the sweet spot of the club head contacts the ball, it will drive the ball further and with more accuracy to its target, because it has no moment of inertia that is creating a torque about the center-line of the shaft.

Claims

1. A ambidextrous golf club assembly is designed so the ambidextrous golfer can use the same golf club as a right hand or left hand golf club. This golf club has a left club head face and a right club head face, which is used to drive a golf ball. The left head face is used by a right hand golfer and the right head face is used by a left hand golfer.
